``A year earlier, that claim was proven false. The CIA knew it. The State Department knew it. The White House knew it.

``But he told us anyway.''

Republicans claim the ad improperly quotes Bush because his entire statement was: ``The British government has learned that Saddam Hussein recently sought significant quantities of uranium from Africa.''

Democratic spokesman Tony Welch said: ``With the British in there, the president's information is still false and misleading. It is exactly what the president said.''

Some Republicans have argued Bush's statement was technically accurate because it attributed the findings about uranium to the British.

``You can say whatever you want in a fund-raiser,'' Republican spokesman Jim Dyke said, ``but it steps over the line when you knowingly mislead people in your advertising.''

Welch said the ad would be aired in Madison, Wis., starting Monday for about a week and the amount spent would be almost $20,000. The ad would be paid for, at least partially, by the Democrats' e-mail campaign, he said.

Efforts to get comment from TV stations in Madison were not successful Sunday.

The ad squabble comes at a time when public trust in the president has been eroding, according to results released Sunday from a CNN-Time poll.

The poll found that 47 percent view Bush as a leader they can trust, while 51 percent said they have doubts and reservations. That's down from 56 percent who saw him as a leader they could trust in late March, with 41 percent having doubts.

The poll of 1,004 people taken Wednesday and Thursday had an error margin of plus or minus 3 percentage points.
